报了这个错误：

 

　　Error: listen EACCES: permission denied 127.0.0.1:80

   　　 at Server.setupListenHandle [as _listen2] (net.js:1273:19)

　　    at listenInCluster (net.js:1338:12)

   　　 at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:62:10)

　　Emitted 'error' event at:

   　　 at emitErrorNT (net.js:1317:8)

在执行 node 1.js前加上sudo
